How to Grow and Care
While this annual can be grown both indoors and out, the most popular use may be as a potted houseplant. Once you look into the native environment for this bright flower, you'll know how to grow Pocketbook Plant. It comes from Central and South America in the cooler plains where water and bright sunlight aren't so abundant. Calceolaria care works best when you try to imitate its native home.
Keep the plant near a bright window but out of direct sunlight. If your only window is on a bright southern exposure, hang a sheer curtain between the plant and outdoors to filter the brightest rays. Northern windows and tables away from the light source are more hospitable for these plants.
Pocketbook Plant care includes carefully monitoring the water supply. These plants don't do well with too much moisture on their roots. Give the plants a thorough watering, then let the pots drain in the sink for about 10 minutes. Allow the soil to dry out until the surface is dry before watering again.
